“ANTI-REFLECTION” COATING FOR A NONLINEAR TRANSMISSION TO TOTAL REFLECTION SWITCH

Abstract

An anti-reflection dielectric coating is designed for a nonlinear interface between a linear and a nonlinear medium. Expressions for the required thickness and refractive indices are derived. It is shown that the appropriately coated system will allow low power light to be initially highly transmitted even for incident angles close to the critical angle for total reflection; the system will also perform the nonlinear transmission to total-reflection switching for high power light.
